Shadow Stoke · Accepted Answer

Final Answer : C, Explanation :  The sum of the frequencies for all classes will always equal the total number of observations in the data set. This is because the frequency of each class represents the number of observations that fall within that class. Therefore, when you add up the frequencies for all classes, you are essentially summing up all the observations in the data set.

The sum of the frequencies for all classes will always equal:

A) the number of classes
B) the class width
C) the total number of observations in the data set
D) one
E) the average
